  1. Fish meat:

– Fresh fish: The flesh is firm, elastic, white, and translucent. It adheres firmly to the bone.

Additional information

Flat fish: In flatfish, loss of firmness, obvious discoloration on the underside, and objectionable odor from the abdominal cavity are symptoms.

Fillets: Stale fillets lose their translucent whiteness, become moist, and crumble, and may emit an unpleasant odor when cut.

Smoke cured fish: Stagnation in smoke-cured fish is indicated by crispness, wet and sticky surface, greasiness in flesh and loss of color. However, it may not have a strong offensive odor due to the natural smoky aroma.

Frozen Fish: High-quality frozen fish should retain its appearance after thawing. Poor quality fish becomes soft, soggy and cracked, losing its fresh and healthy appearance.

In summary, fish inspection involves evaluating odor, appearance, texture, and other physical characteristics to determine freshness or staleness, and this information is critical to ensuring the quality of fish products.
